AH!!! I see. Thanks!
That is pretty much my point that I was trying to make (didn't do a very good job)... I am not knocking 'mil spec' by a mile. Not even close... but there are a bunch of people making things that are to my knowledge technically NOT true mil-spec if you are talking about the letter of it. To my limited knowledge Fathom, Griffin, CMT, and probably a bunch of others have offerings that don't use carpenter steel...
I could be totally wrong but there were a number of people who were throwing out the whole lot because in their view it's 'not as good' or 'inferior' or whatever.
Truth be told I don't know a whole lot about specific working properties of metals. On one of those threads I've seen Griffin getting completely thrown under the bus for even offering a bolt that isn't carpenter steel. Now consider that for a while now I have been running that bolt and carrier that they've been bitching about...
It basically just leads me to think that having an open mind to new offerings isn't always a bad thing. I am generally pretty skeptical myself about some of the stuff I see but every now and then things work out just fine.

Well, part of it is this...we KNOW milspec works, and we know how it works. It is a known quantity. We have all seen things that promise better, and deliver worse. The sharps reliabolt is a perfect example. S7. Broke left and right. Should have been better by a mile. Wasnt.
So, milspec is the easy button, so to speak.
I simply choose to T&E the snot out of something and THEN trust it. That has worked great for me. After a few thousand rounds, I begin to form an opinion of its long term viability. Stuff I have found that offers me value:
A5
Springs action springs
Azimuth qpq bcg
Colt ejector springs
Ken green extractor spring
Badger g3 ch
Badger bolt release
These things have all proven to work very well, but are not milspec necessarily.
Stuff I've had that sucked:
Rubber city armory bcg
Azimuth ejector springs
Milspec action springs on a dirty weapon in humid weather

I called Sharp's today to find out what extractor material they're using right from the horse's mouth, so to speak. Turns out it's NOT C-158 (or perhaps not anymore?) but 4340.
Just thought I'd pass that along.Last edited by Aragorn; 17 October 2016 at 16:45.

So something else all this has me wondering about. Extractor and ejector springs. Here, and pretty much everywhere else, extra power extractor springs always seem to be recommended. Is there any "balancing" that needs to be done with the ejector spring? I.e. if you go to a stronger extractor spring, do you need a stronger ejector spring as well? I was reading elsewhere that in some extreme cases an extra power extractor spring used with an insert and O-ring (which all sounds like overkill to me), that it would "overpower" the ejector spring and cause malfunctions.
I've used extra power extractor springs before from BCM, and I think Springco (I found the slip for one in my spare parts box), and I've just ran them with a black insert and no O-ring. Everything seems kosher. I've also ran BCG's where I haven't changed anything and it still seemed to run fine. I guess I'm just curious from an academic perspective.
Also how do you know if you even need an extra power spring? Ejection pattern? Is it just preventative to ensure positive extraction? I mean I understand you'd use one to cure weak extraction, but are there other reasons to use one? Also read that some of the aftermarket springs were adding a substantial amount of stress to the system.-One Nation, Under God
